River Trent Facts for Kids | KidzSearch.com 1,018.35 m³ / s (35,963 cu ft / s ) 1230hrs on 8 November 2000 - highest discharge since 1 September 1958 The drainage basin of the River Trent --> The River Trent is one of the major rivers of England . It is the third longest river in the United Kingdom . It starts in Staffordshire . It flows through the centre of England until it joins the River Ouse to form the River Humber (estuary) which empties into the North Sea . The name "Trent" comes from a Celtic word possibly meaning "strongly flooding". More specifically, the name may be a contraction of two Celtic words, tros ("over") and hynt ("way"). [1] It is unusual amongst English rivers in that it flows north (for the second half of its route), and is also unusual in exhibiting a tidal bore , the "Aegir". The area drained by the river includes most of the northern Midlands.

Contents 30 fish of the Trent | Canal & River Trust News article created on 17 March 2016 30 fish of the Trent A favourite with anglers is the River Trent, famous for the old 2,000 peg Trent Angling Championships, trotting the stream for roach on the Burton Joyce Golden Mile, and now the haunt of anglers in pursuit of big carp and barbel. Gunthorpe Bridge, River Trent The Trent rises in North Staffordshire, flowing for some 250 miles taking on board waters from the Tame, Dove, Derwent and Soar flowing majestically through Nottingham and Newark before entering the North Sea at the Humber Estuary. The Trent is the third longest river in the United Kingdom and unusually for rivers in Britain, the River Trent flows in a northerly direction. Many years ago, the course of the River Trent was used to mark the boundary between the North and the South of England. 30 species of fish? J W Martin in his 1906 book 'Coarse fish Angling' had an interesting story to tell about the Trent.

According to the 'Trent Otter', the river derived its name from the 30 tributaries, or the 30 abbeys that lined its banks or the 30 species of fish that swam in this wonderful river. From my schooldays the French (Norman) word “trente” means “thirty” so there may be some truth in the statement.

Poet Michael Drayton (1563-1631) put this into a readable verse some three hundred years before Martin: "A more than usual power did in that name consist, Which thirty doth import: by which she thus divin’d There should be found in her, Fishes thirty kind; And thirty abbeys great, in places fat and rank: Should in succeeding time be builded on her bank: And thirty several stream from many a sundry way, Unto her greatness should their wat’ry tribute pay." Edmund Spenser (1590) also stoked the fire: "The Beauteous Trent which in itself enseams, thirty kinds of fish and thirty different streams." Even old Izaak suggested the 30 streams origins and 30 fishes in his book the 'Compleat Angler' of 1653. Would it be so difficult to identify the 30 tributaries, probably long since dried up or now just underground culverts? Or the abbeys, many presumably destroyed by Henry VIII and his dissolution of the monasteries. Being anglers we have more chance with the fish. Or do we?

I've taken a look at the abbeys and come up with nothing. The 30 streams sounds plausible but internet investigations suggest there are more than 30 when counting rivers and their all their tributaries. So back to the fish. Fish in 1641 A 1641 document lists the thirty following fish - Barbet (barbel), Bream, Bullhead, Burbolts (burbot), Carp, Chevin (chub), Crayfish, Dates (dace), Eel, Flounder, Frenches, Gudgeon, Grayling, Lampern (river lamprey), Lamphrey (lamprey), Lenbrood, Loach, Minnows, Pickeral (pike), Pinks (minnow), Perch, Roach, Ruff, Salmon, Shad, Smelt, Sticklebats (stickleback), Sturgeon, Trout, Whitling (young male trout or sea trout?). Of course the Crayfish is an edible crustacean. 'Frenches' and 'Lenbrood' no longer exist in modern English so it is questionable what they are. Striking omissions from the list are bleak and tench.

These old wags included lampreys, smelts and flounders not to mention loaches, miller’s thumbs (bullhead) and sticklebacks. Fish in 1751 By 1751 , Charles Deering provided a revised list of 34 kinds - Barbel, Bream, Bulhead, Burbot, Carp, Chub, Crayfish, Dace, Eel, Flounder, Grayling, Gudgeon, Lamprey, Lampern, Loach, Minnow, Muscle, Perch, Pike, Roach, Rudd, Ruff, Salmon, Salmon Trout, Salmon Pink, Sand Eel, Shad, Smelt, Stickleback, Sturgeon, Stream Pink, Tench, Trout, and Whitling. Once again the tench and bleak are still missing and the salmon is listed under a variety of names. Is the muscle a 'freshwater mussel', stream pink and the 'sand eel' somehow gets into the list? In the old days the sturgeon was a common fish in Europe and would undoubtedly have inhabited the Trent system.

Hugh Sheringham mentions them in his 1912 book 'Coarse Fishing' and other contemporary writers mention the occasional sturgeon entering our river systems. The whale? A 1985 study suggested that about 40 fish species inhabit the Trent, but they were not listed. None of these lists includes the whale. Stop laughing. Two whales were found at Gainsborough in 1938 having come up the Humber estuary. The latest occurrence was in 2003 also in the Gainsborough area. And of course the whale is mammal not a fish. Well that's the 30 fishes idea out of the window. I thought there might be 30 bridges or 'crossings' (fords) on the Trent but that's all conjecture on my part. Today there are reckoned to be 80 bridges that cross the river. More internet research reveals the Trent’s name is derived from 'a Celtic word possibly meaning 'strongly flooding'. 'The name may be a contraction of two Celtic words, tros ("over") and hynt ("way"). This may point to a river that is prone to flooding.

However, a more likely explanation may be that it was considered to be a river that could be crossed principally by means of fords, i.e. the river flowed over major road routes. About this blog John Essex was a key member of the legendary Leicester Likely Lads match team of the 1970’s. He picked up five first division one national championship team medals and was third overall in the 1975 match on the Nene, landing two carp, which was a remarkable angling feat at that time. John coached the Leicester juniors to five NFA junior titles and chaired Leicestershire Angling Federation for nearly 30 years Still fishing weekly at club level, John is an avid collector of books and old tackle with an extensive library of nearly 1000 books. He will be releasing his first book, 'History of the National' shortly. John blogs for us about angling history and heritage.

River Trent - Major Rivers Of The British Isles Major Rivers Of The British Isles Image courtesy of Insignia, wikimedia commons The River Trent is the United Kingdom's third longest river at one hundred and eighty five miles long.The river rises on Biddulph Moor in the county of Staffordshire and flows northwards towards the Humber Estuary, where it meets with the River Ouse at an area called the Trent Falls, before flowing on into the North Sea. The River Trent is unique for being Britain's only north flowing river and for being Britain's most historically important trading river. Looking at a map of the course of the River Trent is akin to taking a study of Britain's Industrial Revolution, as one charts it's route through the industrial heartlands of the English Midlands making it's way through the great industrial towns and cities of Stoke - on - Trent, Nottingham, pictured above, Derby, Burton and Newark. For half of it's route the River Trent is freshwater and non tidal, but after passing through the town of Newark in Nottingham, the River becomes non navigable, northwards flowing and tidal.

During the month of September the river is the location of Britain's third largest tidal bore, The Trent Aegir or Trent Bore, pictured below, which can rise to over five feet in height and travel as far inland as Gainsborough in Lincolnshire. Image courtesy of Nigel Homer, wikimedia commons The river's name comes from a Celtic word which means strong flood, a name which was probably attributed to the aftermath of it's annual tidal bore, which would have caused great floods along it's tidal route, particularly on the low lying lands of the county of Lincolnshire.The river was for centuries considered the ancient north / south divide of England and was known as Trisantona in Roman times. The river connects with forty two tributaries along it's route, including the Rivers Derwent, Dove, Soar and Tame. At the beginning of the Industrial Revolution, during the 1770's, the river became linked to six canal systems, including the Trent and Mersey Canal, The Bridgewater Canal and The Nottingham Canal.

The river is crossed by way of eighty one bridges, including Britain's longest, stone bridge, the Swarkestone Bridge, a one mile long, thirteenth century, seventeen arched, local stone built bridge, which is now a Grade 1 listed building, situated six miles north of the city of Derby. Along with the building of the canal system, the River Trent's riverbanks were also chosen to house the sites of 1thirteen beautifully constructed, industrial power stations - most of them no longer in use - pumping engines, locks and weirs, all of which still remain as a testament to the river's industrial history. The riverbanks in recent years however, have been chosen for the sites of seven national Nature Reserves and country parks, that between them cover over one thousand acres of prime riverside and estuary land, which include the four hundred and seventy four acre Blacktoft Sands RSPB Reserve in Yorkshire, and the three hundred and sixty acre Attenborough Gravel Pits Wildlife Reserve in Nottinghamshire.

River Trent | Fallons Angler Fallons Angler Return to Content River Trent By Fishpool on July 15, 2015 in Bits ‘n Pieces Issue 16 , BITS’N’PIECES , PLACES WE LIKE The Mighty Trent – it is an apt moniker. The Trent is the UK’s third longest river and drains a vast area of central England. From its source at Biddulph Moor in Staffordshire, the river works its way north-east, picking up tributaries such as the Derbyshire Derwent, Dove, Idle, Mease and Soar, before emptying into the Humber Estuary. As a fishery it pretty much has it all – and is regarded historically as one of the finest fishing rivers in Britain. Izaak Walton was most complimentary – One of the finest rivers in the world and the most abounding with excellent salmon and all sorts of delicate fish. Today the salmon, with a little help, are making a comeback and all the while the coarse anglers are plundering an extraordinary stock of fish. Huge barbel, chub, carp and pike have specimen hunters licking their lips, while the matchmen come for the dace, roach and bream.

The water of the Trent is truly special and fortunately Man discovered long ago that it makes rather good beer. There are some corking ales out there, Fishpool rather fancies a pint of Halcyon Daze…… Subscribe Rivers Avon (Bristol) From the Kennet & Avon Canal at Hanham Lock the River Avon runs for 13.75 miles to the Bristol Channel and then into open sea. The wonderful city of Bristol is steeped in maritime and engineering history, much of which is attributable to Isambard Kingdom Brunel . Brunel's incredible suspension bridge at Clifton is a spectacle never forgotten. Bristol Docks have undergone modernisation and the famous 18th Century statue of Neptune, originally erected in the Temple area, is now part of a pedestrianised city centre. Avon (Stratford) Upper Avon or Warwickshire Avon River in southern England; length 154 km / 96 miles.

Sometimes known as the Upper Avon or Warwickshire Avon, it rises in the Northamptonshire uplands near Naseby and flows southwest through Warwick, Stratford-upon-Avon, and Evesham, before joining the River Severn near Tewkesbury, Gloucestershire. One of Britain's most secluded cruising rivers, the Avon meanders past ancient towns and through picturesque countryside. It flows through Stratford, Evesham and Pershore to Tewkesbury, where it meets the mighty River Severn . Its surroundings have changed little since the days of its most famous son, William Shakespeare. The Avon is a popular river with motor cruisers and narrowboats, but the wide valley and peaceful villages give it an untroubled air that makes it one of Britain's most relaxing waterways. Though there is no continuous towpath, there are many walking opportunities. It is often known as Shakespeare's Avon or simply the 'Stratford Avon', because Avon is such a common river name - deriving from Afon, the Welsh for 'river'.

Calder River in West Yorkshire, England; length 72 km / 45 miles It rises in the Pennine moors northwest of Todmorden, and joins the River Aire at Castleford. Several large reservoirs supplying water to West Yorkshire towns lie within its catchment area. The Aire and Calder Navigation forms a link in the system of rivers and canals that provides a waterway from the River Mersey to the River Humber. The Calder valley, via Hebden Bridge, Sowerby Bridge, Mirfield, to Wakefield, is one of the main road and rail routes through the Pennines. Calder River in Cumbria, England. It flows into the Irish Sea 16 km / 10 miles southeast of Whitehaven. Calder River in central Lancashire, England; length 24 km / 15 miles It joins the River Ribble near Whalley. Cam River in southeast England. It rises in Ashwell, Hertfordshire, and flows 65 km / 40 miles northwest and northeast through Cambridgeshire, and then into the River Ouse, 6 km / 4 miles south of Ely.

The Cam is joined at Hauxton by the River Granta, which rises in Essex, and is known thereafter as either the Cam or the Granta. It is navigable as far as the city of Cambridge. Dee (Cheshire) The River Dee passes through magnificent borderland scenery as it tumbles from Llyn Tegid (Bala Lake) through Llangollen to Chester and the sea. Along its way, it passes over Horseshoe Falls and under the Pontcysyllte Aqueduct, two landmarks around the charming town of Llangollen. The Dee can be navigated by all craft from Farndon, in rural Cheshire, through Chester and out to the sea. The upper reaches are prized by canoeists, though access rights are hotly debated. Dee (Scotland) The fifth longest river in Scotland, the Dee flows through some of the most stunning scenery in Scotland on its journey from the Cairngorm Mountains to the North Sea at Aberdeen. Fast-flowing and rocky at times, the River Dee has an abundance of character that is magnificent. It is not uncommon to see canoeists paddling down along the river.

The �Royal Dee' is overlooked, at parts, by the magnificent Balmoral Estate, which offers angling and also some impressive marked walks. Balmoral Castle has been enjoyed by generations of royals since Queen Victoria. Dove River in Derbyshire, England, a tributary of the Trent; length 65 km / 40 miles. The Dove rises on Axe Edge, 6 km / 4 miles from Buxton, and forms the southwestern border between Derbyshire and Staffordshire as it flows south to join the Trent near Burton. The valley of Dovedale, below Hartington, where the river runs through a rocky, wooded gorge some 3 km / 2 miles long, is popular with walkers. Fal For more than 2,000 years the River Fal was the life-blood of the Cornish community between Truro and Falmouth. Today, the tourist town of Falmouth is known as the sailing and yachting capital of the county. Luxury vessels line the Fal Estuary � the third largest natural harbour in the world � and pretty yachts congregate during the Falmouth sailing regatta.

Back in the 17th Century, Falmouth was famed for its Post Office Packet sailing boats which carried mail and cargo to and from places as far afield as the East Indies. Boats have travelled up the Fal to the port of Truro since the bygone days of 1170, and vessels approaching 85m in length still regularly sail upstream into the city. The traditional industries of ship repair, cargo handling and yacht building continue to bring money into Falmouth, and old-fashined oyster boats can still be seen trailing the river and charming onlookers. However, the town and the area surrounding the river are now largely dependent on tourism. Cornwall is an ever popular holiday destination � especially during the summer months � and the Fal's maritime traditions, picturesque harbours and interesting towns win the hearts of visitors year after year. Great Ouse River which rises near Brackley in Northamptonshire, central England, and flows eastwards through Buckinghamshire, Bedfordshire, Cambridgeshire, and Norfolk, before entering the Wash north of King's Lynn; length 250 km / 160 miles.

A large sluice across the Great Ouse, near King's Lynn, was built as part of extensive flood-control works in 1959. The chief tributaries of the Great Ouse are the Ivel, Cam , Lark, Little Ouse, Wissey, and Nar, all of which come from the south or east. The Bedfordshire Ouse was diverted in the 17th century from its devious course through Ely via two new channels called the New and Old Bedford rivers, 32 km / 20 miles long, running in a direct line from Earith near St Ives to Denver Sluice near Downham Market. Hamble For 7.5 miles from Botley to Southampton Water, the River Hamble offers facilities for sea-going vessels in scenic surroundings that are very popular especially in the high season. It's known throughout the yachting world as the Heart of British Yachting. The river's position makes it suited both for weekend trips and as a base for international yachtsmen. There are numerous festivals and regattas throughout the year. The entrance to the River is illuminated with sector lights at Hamble Point and Warsash.

Manifold River which flows through the Manifold Valley, a limestone gorge situated at the southern end of the Peak District in Staffordshire, England. For a distance of about 1.5 km / 1 miles the river disappears underground in swallow holes for part of the year. Mersey River in northwest England; length 112 km / 70 miles. Formed by the confluence of the Goyt and Tame rivers at Stockport, it flows west through the south of Manchester, is joined by the Irwell at Flixton and by the Weaver at Runcorn, and enters the Irish Sea at Liverpool Bay. It drains large areas of the Lancashire and Cheshire plains. The Mersey is linked to the Manchester Ship Canal. Although plans were announced in 1990 to build a 1,800-m / 5,907-ft barrage across the Mersey estuary to generate electricity from tides, these were abandoned in 1992 for financial reasons. The river lies entirely below 45 m / 150 ft. It is artificially modified (as part of the Manchester Ship Canal) as far as Warrington, where it becomes tidal.

The Mersey is polluted by industrial waste, sewage, and chemicals. The Mersey became an artery of communications from the 18th century. Boats for passengers and goods used the river, with its major tributary the Irwell, between Liverpool and Manchester from 1720; the Bridgewater Canal acquired this traffic in the late 18th century. The Mersey had passenger services until the development of the railway in the middle of the 19th century. In the estuary (which has an area of over 78 sq km / 30 sq miles), steam ferries provided transport for commuters from the residential areas of Cheshire to Liverpool from 1815. In 1934 the first road tunnel under the Mersey was opened. Until the 1920s the river formed the boundary between Lancashire and Cheshire. Nidd River in North Yorkshire, England, located within the Yorkshire Dales National Park. The river flows southeast from the base of Whernside (27 km / 17 miles northwest of Ripon) into the River Ouse near York. Water is supplied to Bradford from a dam above the village of Pateley Bridge.

Upper Nidderdale is a designated area of outstanding natural beauty. Nith River of southern Scotland, rising in East Ayrshire unitary authority, about 13 km / 8 miles south of Cumnock, and flowing southeast for about 112 km / 70 miles through the valley of Nithsdale in Dumfries and Galloway unitary authority, before entering the Solway Firth 13 km / 8 miles south of Dumfries. Severn Welsh Hafren Longest River in Britain , which rises on the slopes of Plynlimon, in Ceredigion, west Wales, and flows east and then south, finally forming a long estuary leading into the Bristol Channel; length 336 km / 208 miles. The Severn is navigable for 290 km / 180 miles, up to Welshpool (Trallwng) on the Welsh border. The principal towns on its course are Shrewsbury, Worcester, and Gloucester. England and South Wales are linked by two road bridges and a railway tunnel crossing the Severn.

A remarkable feature of the river is a tidal wave known as the `Severn Bore� that flows for some miles upstream and can reach a height of 2 m / 6 ft. The Severn rail tunnel was built in 1873-85. The first of the road bridges to be built opened in 1966, and carries the M4 motorway linking London and South Wales. A second road bridge was opened in 1996 and carries the M48 motorway. From its source, the Severn passes east through Powys and enters Shropshire near the Brythen Hills. Southeast of Shrewsbury, the river passes through Ironbridge Gorge, `cradle of the Industrial Revolution� and now a tourist attraction. Thereafter, it runs through Worcestershire and Gloucestershire, widening considerably after it passes Newnham. The Severn is navigable by larger ships (of around 8,000 tonnes) as far as Sharpness, and by smaller vessels (up to 700 tonnes) to Gloucester, while barges of 350 tonnes capacity can negotiate its upper reaches as far as Stourport.

The Severn is connected with the rivers Trent and Mersey via the Staffordshire and Worcestershire Canal , and with the canal network around Birmingham via the Worcester and Birmingham Canal , which joins the Severn at Worcester. Between Gloucester and Sharpness, the treacherous nature of the riverbed necessitated the construction, in 1827, of the 26 km / 16 mile long, lock-free Sharpness and Gloucester Ship Canal. Tributaries of the Severn include the Teme, Stour, Wye , Vyrnwy, Tern, and Avon; in total, the river basin covers an area of 11,420 sq km / 4,409 sq miles. Crossings Between 1873 and 1885, a rail tunnel was dug underneath the Severn near Chepstow, running for a distance of 7.2 km / 4.4 miles, from New Passage to Portskewett; this crossing greatly facilitated travel between Bristol and the Welsh capital Cardiff.

A road suspension bridge was opened nearby, from Aust to Beachley, in 1966; this crossing carries the main M4 motorway linking London and South Wales and is subject to payment of a toll by users. Because of the increase in traffic volume, construction of a new road bridge was started in 1992 and completed five years later. Hydroelectric power In 1933, a committee recommended the construction of a hydroelectric power station on a river barrage at English Stones reef, which would utilize the tidal flow of the Severn. This plan, which was interrupted by World War II, was revived in 1945, when engineers confirmed the practicability of the scheme and projected an output of some 2,190,000,000 kWh. However, no tidal power plant has yet been built. Spey Second longest river in Scotland. It flows through Highland and Moray, rising 14 km / 8 miles southeast of Fort Augustus, for 172 km / 107 miles to the Moray Firth between Lossiemouth and Buckie. It has salmon fisheries at its mouth. The upper river augments the Lochaber hydroelectric scheme.

Whisky is distilled in the Spey valley. Taf River in Carmarthenshire, southwest Wales, rising on the eastern side of the Preseli Hills and flowing through Carmarthenshire to Carmarthen Bay; length 50 km / 31 miles Commercial fisheries operate in Carmarthen Bay. The village of Laugharne lies at the mouth of the river. Tay Longest river in Scotland ; length 193 km / 120 miles, it flows northeast through Loch Tay, then east and southeast past Perth to the Firth of Tay, crossed at Dundee by the Tay Bridge, before joining the North Sea. The Tay has salmon fisheries; its main tributaries are the Tummel, Isla, and Earn, Braan, and Almond. The drainage basin of the Tay and its tributaries forms one the most fully integrated hydroelectric developments in the north of Scotland. The first Tay Bridge, opened in 1878, on the then longest span over water in the world, was blown into the river in 1879, along with a train which was passing over it.

The bridge was rebuilt in 1883-88, and a road bridge, from Newport-on-Tay to Dundee, was completed in 1966. Tees River flowing from the Pennines in Cumbria, northwest England, to the North Sea via Tees Bay, Middlesborough unitary authority, in northeast England; length 130 km / 80 miles. Its port, Teesport, handles in excess of 42 million tonnes per annum, with port trade mainly chemical-related. Although much of the river nearing the sea is polluted with industrial waste, sewage, and chemicals, the Tees Barrage (opened in 1985, cost of construction �50 million) enables a 16 km / 10 mile stretch of the river to provide clean, non-tidal water. This is used for white - water sports, including canoeing. The Tees rises in the north Pennines at Tees Head, on the easterly reaches of Cross Fell, Cumbria, and flows southeast and then northeast through Stockton-on-Tees and Middlesbrough, entering the Tees Mouth estuary to join the North Sea.

It is navigable to Middlesbrough. Its main tributaries are the Lune, Balder, and Greta. The river valley, known as Teesdale, includes Mickle Fell (790 m / 2,326 ft), the highest point in County Durham, and the waterfall of High Force. The Tees has a unique transporter bridge (a bridge consisting of a movable platform suspended from cables), opened in 1911, which has 49 m / 160 ft clearance above the water. Its central section transports cars and people across the Tees towards Hartepool. It is the sole working example in England. Teme The river Teme is the second largest tributary of the River Severn . It rises in the Kerry hills in Mid Wales from a small spring in Bryn Coch quarry on Cilfaesty Hills at 460 metres above sea level. The Teme is a rural river flowing through unspoilt countryside which is regarded as some of the most attractive in Britain. The main town on the Teme is the historic border town of Ludlow in Shropshire.

The Teme Valley, running down from Ludlow, comprises of the orchards, woods and countryside of Herefordshire and Worcestershire, to the foothills of the Malverns, the valley of the River Teme is an area of great beauty, interesting architecture, quiet places and rural pursuits. The rural nature of the river is reflected by high quality water with excellent brown trout and grayling fishing, with a challenge for the purist angler willing to accept the rugged conditions. Thames River in south England, flowing through London; length 338 km / 210 miles. The longest river in England , it rises in the Cotswold Hills above Cirencester and is tidal as far as Teddington. Below London there is protection from flooding by means of the Thames Barrier (1982). The headstreams unite at Lechlade. Tributaries from the north are the Windrush, Evenlode, Cherwell, Thame, Colne, Lea, and Roding; and from the south, the Kennet, Loddon, Wey, Mole, Darent, and Medway. Around Oxford the river is sometimes poetically called the Isis.

The construction of a 11 km / 7 mile flood alleviation channel between Maidenhead and Eton was approved in 1994. At Gravesend, the head of the estuary, it has a width of 1 km / 0.6 miles, gradually increasing to 16 km / 10 miles at the Nore. Lying some 5 km / 3 miles southwest of the Nore is the mouth of the Medway estuary, at the head of which lie Chatham with important naval dockyards, Gillingham, and Rochester. Gravesend on the south bank of the river, some 40 km / 25 miles from the Nore, developed at a point where vessels used to await the turn of the tide. Tidal waters reach Teddington, 100 km / 62 miles from its mouth, where the first lock from the sea (except for the tidal lock at Richmond) is located. There are in all 47 locks, St John's Lock, Lechlade, being nearest the source.

The normal rise and fall of the tide is from 4.5 m / 15 ft to 7 m / 23 ft at London Bridge and from 4 m / 13 ft to 6 m / 20 ft at Tilbury. Until Tower Bridge was built, London Bridge was the lowest in the course; the reach between these two bridges is known as the `Pool of London�. Tilbury, Fort and Docks, important as the main London container terminal, lies opposite Gravesend on the northern bank. At Woolwich, some 30 km / 19 miles above Tilbury, is the arsenal; Greenwich, a little farther upriver, has the Royal Naval College. Between Tilbury and London Bridge (some 40 km / 25 miles upstream) stretches the London dock System. The Thames has been frozen over at various times, the earliest recorded occasion being AD 1150. The embankments of the Thames in London were the work of Sir Joseph Bazalgette (1819-91), chief engineer of the Metropolitan Board of Works.

The Albert Embankment on the south side was completed in 1869, the Victoria Embankment from Westminster to Blackfriars in 1870, and the Chelsea Embankment from the Royal Hospital to Battersea Bridge in 1874. In January 1949 work was started on a new embankment, designed by J Rawlinson, chief engineer of the former London County Council, on the south side from County Hall to Waterloo Bridge. These embankments were raised after 1974. There are walkways (formerly towpaths) from Teddington to Cricklade. The Port of London Authority is responsible for the control and conservation of the river below Teddington. Above Teddington the Environment Agency is the responsible authority; there is some barge traffic on this stretch of the river. The Thames is of great importance to the water supply of London, partly because the many springs in the chalk usually maintain a steady flow in summer. Salmon returned to the Thames in 1974. The river is spanned by 20 road and nine rail bridges between Hampton Court and the Tower of London.

These include Tower Bridge (which has a drawbridge mechanism to enable large vessels to pass) and a suspension bridge at Hammersmith. The QEII Bridge opened in 1991 joins the counties of Essex and Kent. The chief tunnels under the Thames are the Thames Tunnel, completed by Brunel in 1841, now used by the East London Line of the London Underground; the Blackwall Tunnel (1897) from East India Dock Road to East Greenwich, the Rotherhithe Tunnel (1918) from Shadwell to Rotherhithe, and the Dartford tunnel completed in 1963. There are regular boats from Kingston to Folly Bridge, Oxford, during the summer. There is some beautiful scenery along this part of the river, for example at Cliveden, Cookham, Sonning, and Pangbourne. There are fine bridges at Richmond, Hampton Court, Chertsey, Maidenhead, and Shillingford. Henley , Wallingford, Dorchester, Abingdon, Eton and Windsor are attractive. The Royal Regatta at Henly on Thames is one of the highlights of the British social calander.

Along the 80 km / 50 miles from its source beneath a tree in `Trewsbury Mead� to Oxford, the Thames glides through meadows, its course interrupted only by the small towns of Lechlade and Cricklade and the pretty stone-built hamlets of Kelmscott and Ashton Keynes. In these upper reaches there are two medieval bridges New Bridge and Radcot Bridge. Motor launches can reach Lechlade; beyond that point it is possible to canoe up to Cricklade, but the final 16 km / 10 miles to the source of the Thames is best done on foot. One particularly attractive section is the steep-sided valley through the chalk hills between Goring and Reading, known as the Goring Gap. Trent Third longest river of England; length 275 km / 170 miles. Rising in the south Pennines (at Norton in the Moors) by the Staffordshire-Cheshire border, it flows south and then northeast through Derbyshire, along the county boundary of Leicestershire, and through Nottinghamshire and Lincolnshire, joining the Ouse east of Goole to form the Humber estuary, and entering the North Sea below Spurn Head.

Its drainage basin covers more than 10,000 sq km / 4,000 sq miles. Main tributaries are the Churnet, Dove , and Derwent. It is navigable by barge for nearly 160 km / 100 miles. The principal towns and cities along its course are Burton upon Trent, Stoke-on-Trent, Nottingham, and Newark. It is connected with other rivers and with the Birmingham and Lancashire districts by the Trent and Mersey Canal and the Grand Union Canal . The Trent valley includes extensive gravel workings and many electric power stations. Tweed River rising in the Tweedsmuir Hills, 10 km / 6 miles north of Moffat, southwest Scottish Borders, Scotland, and entering the North Sea at Berwick-upon-Tweed, Northumberland; length 156 km / 97 miles. It flows in a northeasterly direction, and from Coldstream until near Berwick-upon-Tweed it forms the border between England and Scotland. It is the fourth longest river in Scotland and is one of the best salmon rivers.
